Hornady GMX Bullets 8mm (323 Diameter) 180 Grain GMX Boat Tail Lead-Free Box of 50

Hard-hitting and deep-penetrating, the Hornady GMX bullet combines monolithic construction with pioneering ballistic design to meet the need for a premium, non-traditional bullet. The mono-metal design of the GMX bullet is crafted from a copper alloy. Harder than solid copper, the copper/zinc alloy has been proven to shoot cleaner, foul less, and deliver consistent, even pressure curves. The tough alloy material routinely retains 95% or more of its original weight and expands up to 1.5 times its original diameter.
